BROODER.

Specification of Letters Patent.

Patented Dec. 29, 1908.

Application filed September 19, 1906.` Serial No.l 335,319.

To all 'whom it may concern:

Be it known that I, FAY T. PORTER, a citizen of the United States,residing at Morristown, in the county of Shelby and State of Indiana,have invented certain new and useful Improvements in Brooders, of whichthe following is a specification.

This invention relates to new and useful improvements in poultrybrooders.

The invention alms as a primary object to provide in connection with anelectric alarm for indicating the heat, which is the subject of a priorpatent, a novel heat regulating means actuated by an element of saidalarm.

The invention further aims to provide a device that shall be inexpensiveto manufacture and practical and efficient in use.

The detailed construction will appear in the course of the followingdescription in which reference is had to the accom anying drawingsforming a part of this specification, like numerals designating likeparts throughout the several views, wherein,

Figure 1 is a central longitudinal section of a brooder-constructed inaccordance with my invention, and Fig. 2 is a detailed longitudinalsection of a heat regulating means embodied in my invention.

Referring specifically to the accom anying drawings, the numeral 1designates t e body of the brooder, which is supported upon legs orcorner posts 2. The body 1 is provided along its upper edge with alateral flange 3 extending on all sides thereof to which is removablysecured a closed u per portion 4 which forms a roof for the brooder andis provided with a horizontal plate or partition 5 supported upon aledge 6 and serving as a ceiling for the body 1. The ceiling 5 alsoserves incidentally as a support for the various elements of theinvention. To this end a vertical heating drum 7, provided with a bottom8, and an open upper end is projected therethrough. rThe drum 7 in itslower portion communicates with a tubular ipe 9 leading from a flue 10also projecting t rough 4the ceiling 5 and provided at its lower endwith a flared extension 11 surrounding the chimney 12 of a lamp 13supported u on the floor of the body 1 and serving for ighting andheating purposes. The top late of the roof 4 is protected from the heaty suitable guards 14 disposed above the drum 7 and iiue 10.4 Athermostatic lever 15 is pivotally mounted within the roof 4 upon asuitable support 16 and at its end is provided with a shoe or plate. 17placed directly above the flue 10. From the element 15 a sliding gate 18is suspended by means of a rod or other suitable connection 19. The rod19 works in an opening 2() in the pipe 9 and the gate 18 has transversemovement with relation to said pipe. In such action said gate serves asa damper to regulate the heat in the well known manner. Aside from thisfunction as a thermostatic damper regulator, the lever 15 is alsodesigned to sound an alarm by virtue of the electrical connectionstherewith in its extreme expansive and retractile movement. To this enda battery 21 is provided from which leads a wire 23 having permanentconnection with the lever 15 as at 24, adjacent the support 16 of saidlever, and a wire 22 having connection with a post 25 from which spacedcontacts 26 are supported in superposed relation.

The body 1 is provided with a door 27, a Window 28 for admitting lightin the day time and an air register 29. The lamp 13 serves to aord lightat night to prevent the fowls from crowding. The roof 4 is provided withan opening 30 through which bad air passes from the brooder, adeflecting plate 31 being mounted in front of said opening within thebrooder. It is preferred to have the roof 4 removable as shown byproviding bolt and nut connections 32 engaging in sheared recesses 33disposed in registering relation in the flange 3 of the body portion 1and in a confronting flange 34 of the roof 4. If desired the roof may behinged or pivoted.

The operation will be readily apparent. The ceiling 5 serves as adistributing plate for the heated air circulating within the roof and inthis function co-acts with the drum 7. Whenthe heat becomes excessivethe lever 15 expands and rocks upwardly on its pivot so as to engage theuppermost contact 26 and thereby complete the circuit so as to ring thebell 35 interposed in the wires 22 and 23. In this action, the lever 15raises the gate 18 and shuts off the heat from the drum 7 as will bereadily understood. When the temperature falls below a pre determineddegree, the lever 15 contracts and rocks downwardly on its pivot so asto engage the lower contact 26 and sound the alarm 35 in the samemanner.

In this action the gate 18 moves downwardly so that communication isestablished between the flue l0, the pipe 9 and the drum 7.

While the elements herein shown and described are well adapted to servethe functions set forth, it is obvious that various minor changes may bemade in the proportions, shape and arrangement of the several partswithout departing from the spirit and scope of the invention as dened inthe appended claims.

Having fully described my invention l claim:

1. ln a broeder, the combination of a easing, a source of heat in saidcasing, a second closed casing superposed upon said first named easing,a flue leading from said source of heat upwardly through the base ofsaid last named easing, a heat service pipe within said irst namedeasing, and leading from said flue, a damper in said service pipe, athermostatic bar arranged in said last named easing having one end fixedand having its other end provided with a plate disposed above the upperend of said ilue within said last named easing, and a positiveconnection between said thermostatic bar and said dam- 1 per, leadingthrough the base of said last named chamber within said 'lirst namedchamber, substantially as described.

2. In a brooder, a casing having an outwardly flanged upper edge, asource of heat in said casing, a second closed easing mounted upon saidflange of said first named easing, a llue leading from said source ofheat upwardly, through the base of said last named casing, a heatservice pipe within said irst named easing, and leading from said i'lue,a damper in said service pipe, a thermostatic bar arranged in said lastnamed easing having one end iixed and having its other end provided witha plate disposed above the upper end of said llue within said last namedcasing, and a positive connection between said thermostatie bar and saiddamper, lxading through the base of said last named chamber within saidfirst named chamber, substantially as described.
